I have a menu activity that acts as a level selector. When the user finishes a level (activity) and returns to the menu, I want it to set an image visible in the menu to show that said level has been completed. Also, I want this info to save from a session to another.
My aproach has been to try SharedPreferences. This is the code from the level activity that writes the save:
private int levelNumber
SharedPreferences save = getSharedPreferences("SaveGame", MODE_PRIVATE);
SharedPreferences.Editor editor = save.edit();
editor.putInt("levelComplete",levelNumber);
editor.commit();
GameActivity.this.finish();
This is the relevant code from the menu that reads the save and sets the image visible based on the levelNumber:
clear_stage = new ImageView[clear];
clear_stage[0] = (ImageView)findViewById(R.id.clear1);
clear_stage[1] = (ImageView)findViewById(R.id.clear2);
clear_stage[2] = (ImageView)findViewById(R.id.clear3);
clear_stage[3] = (ImageView)findViewById(R.id.clear4);
clear_stage[4] = (ImageView)findViewById(R.id.clear5);
SharedPreferences save = getApplicationContext().getSharedPreferences("SaveGame", MODE_PRIVATE);
clear = save.getInt("levelComplete", 0);
clear_stage[clear].setVisibility(View.VISIBLE);
I have the visibility set to "gone" in the xml, by the way.
Now, my main problem is that the visible image changes every time that a level is completed, and the last image goes invisible again (gets overwritten). Is there a way to store the clear value each time a level is complete?
I tried with:
SharedPreferences saveall = getSharedPreferences("SaveGame", MODE_PRIVATE);
SharedPreferences.Editor editor = saveall.edit();
editor.putInt("clear_stage",clear);
editor.commit();
But it isn't working, and I don't really know what I should do next. Ask me anything if the post wasn't clear enough.
